The effect of fuel injection equipment on the dispersed phase of water-in-diesel emulsions by Ismael, M.A., Heikal, M.R., Aziz, A.R.A., Syah, F., Zainal A., E.Z., Crua, C.

“…We varied the water mass fraction (5, 10 and 15 by volume) of the emulsion and the injection pressure (500, 1000 and 1500 bar), imaged the samples using a high-resolution microscope and extracted the droplet size distribution using a purpose-built image processing algorithm. …”
